Apocalypse: Let Me Loot All the Treasures

Lu Yang: "Wishing all my readers overflowing wealth and success in everything! May you enjoy peace year after year, get everything you wish for, stay safe and happy, see your wishes fulfilled, grow richer by the day, earn a fortune, enjoy booming business, rise higher at every step, have a bright future, achieve great things, and enjoy health and longevity! Thank you very much!"

(Two protagonists, no CP. Occasionally a little unhinged + System + reborn + treasure hunting + team-ups. There is both decisive ruthlessness and saintly compassion. The plot has a bit of everything, and the opening is a fairly typical setup.)

The protagonists' values aren't too extreme, and they aren't particularly twisted either. You could say they're just a little ill.

In his previous life, Lu Yang climbed from a ranking of tens of thousands into the top ten while dragging along his father, who'd given up on life. But his father, busy chasing internet celebrities, attacked from behind during a crucial battle and stole Lu Yang's precious artifact, causing Lu Yang's gruesome death.

In this life, we're even. With no deadweight holding me back, I'll take everything that should have been mine!
